Slide fastener and slide fastener article coated

Technical field

The present invention relates to the slide fastener being configured with former code in the end side of chain denture, particularly the pull head slided along chain denture can be stopped and the slide fastener kept by former code.

Background technology

In Japanese Patent Publication 4-84313 publication (patent document 1), disclose following training pants (training trousers): in order to training pants can be put under the states such as sports footwear, spikes and can at once take off wearing, at left and right leg, slide fastener is installed, thus front body piece and rear body piece can be opened into.

About training pants disclosed in this patent document 1, more specifically describe, as shown in figure 19, in the left and right sides of training pants 60, being provided with in the scope of the bottom of bottom of s trouser leg side in the upper end of the waist side from this training pants 60 can the slide fastener 61 of opening and closing.Therefore, by making the pull head 62 of each slide fastener 60 slide, the chain denture being in engagement is separated, thus training pants 60 can be opened into front body piece 63 and rear body piece 64 from the form of trousers.

In addition, open like this and the front body piece 63 of the state that obtains and rear body piece 64, make mutually corresponding chain denture be engaged with each other thus be linked up, so training pants 60 can be returned to the trousers form shown in Figure 19 by making the pull head 62 of described slide fastener 61 slide.

There is the training pants 60 of the patent document 1 of such structure, under the blocking of the slide fastener 61 of the left and right sides, can put in the same manner as existing common training pants 60, take off.In addition, this training pants 60, opens front body piece 63 and rear body piece 64, even if wearing under the states such as sports footwear, also can easily take off by slide fastener 61.

But slide fastener just uses in the goods in various field all the time, in addition, slide fastener self is also improved according to the goods that will use, thus has various function.Such as, following slide fastener is disclosed: in the upper end side of chain denture, former code be installed and pull head slided and pull head is departed from along chain denture from former code side, the chain denture of left and right being separated from former code side slidably of pull head can not relied on thus in Japanese Patent Publication 41-9266 publication (patent document 2).

This slide fastener described in patent document 2, is commonly called top-opening type slide fastener, even if do not make pull head slide as existing common slide fastener, and by being pulled to the direction be separated from each other by the zipper teeth chain of left and right, also chain denture can be separated and unzip.Therefore, top-opening type slide fastener, such as, uses in the goods that the life vest that needs are tackled fast when urgent etc. are such.

And, describe the invention relevant to the former code used in top-opening type slide fastener in this patent document 2.This former code described in patent document 2, as shown in figure 20, the 2nd former code portion 75 that there is in mutually relative mode the 1st former code portion 74 on the zipper teeth chain 73 being fixed on left side and be fixed on the zipper teeth chain 73 on right side.

1st former code portion 74 has through through hole 76 on band table back of the body direction, and is configured to be pressed by the 2nd former code portion 75 and can elastic deformation.2nd former code portion 75, has and is configured in jut 77 on the side wall surface relative with the zipper strip of the other side and protrusion 78, and be configured to press the 1st former code portion 74 by protrusion 78.

There is the slide fastener 71 of such former code, by making pull head 72 to the engagement direction of chain denture (in figure, upper direction) slide, 1st and the 2nd former code portion 74,75 is entered from the shoulder mouth of pull head 72 respectively, and then the 1st former code portion 74 and the 2nd former code portion 75 mutually abut and be pushed on the flange 72a of the left and right of pull head 72, thus pull head 72 can be made to stop in the position of regulation.

Then, by the halted state from the pull head 72 shown in Figure 20 by pull head 72 powerful pull-up upward, the 1st and the 2nd former code portion 74,75 is pushed and close to each other.Now, the 1st former code portion 74 is by protrusion 78 elastic deformation from side wall surface thruster pressure in the 2nd former code portion 75, thus the 1st and the 2nd former code portion 74,75 can by pulling out from the deutostoma of this pull head 72 between the left and right flange 72a of pull head 72.

Thus, pull head 72 can cross the 1st and the 2nd former code portion 74,75, and moves to the upper side in the 1st and the 2nd former code portion 74,75, is pulled out by the chain tooth path of navigation of the chain denture in left side from pull head 72.Therefore, by being pulled open to the direction be separated from each other by the zipper teeth chain 73 of left and right afterwards, the chain denture of left and right can be made to be separated from upper side, thus can not rely on pull head 72 slidably rapidly and easily open slide fastener 70.

On the other hand, in Japanese Unexamined Patent Publication 6-14806 publication (patent document 3), disclose following technology: a kind of at middle slide fasteners used such as automotive seats, can pull head be made from the pull-off of slide fastener long-chain after making the engagement of the chain denture of left and right.

In this slide fastener 81 described in patent document 3, as shown in figure 21, in the end side of the chain denture of left and right, former code 82 is installed, code 83 after another side is provided with.Described former code 82 has: be fixed on the zipper strip in left side, have the 1st former code portion 84 of engaging recessed part; Be fixed on the zipper strip on right side, there is the 2nd former code portion 85 of engaging protrusion.

In addition, this former code 82 is set as, embed in the engaging recessed part in the 1st former code portion 84 making the engaging protrusion in the 2nd former code portion 85 make the 1st and the 2nd former code portion 84,85 mutual locking time, the gauge of former code 82 entirety and width dimensions are the gauge identical with the slide fastener coupling element of the left and right being in engagement and width dimensions.Thus, make the 1st and the 2nd former code portion 84,85 locking time, not shown pull head easily can pass through former code 82, so pull head can be made from the pull-off of slide fastener long-chain.

And in the slide fastener 81 of patent document 3, the band upper end 86 being configured with former code 82 of zipper strip, the band portion of its left and right sides is cut, and is formed as mountain shape in the mode that the band portion of the central authorities with former code 82 is outstanding.Give prominence to by making the band portion of the central authorities with former code 82 like this, when the slide fastener 81 (slide fastener long-chain) of the state after pull head pull-off is subject to lateral pull, this lateral pull can be made to be difficult to act on former code 82, so the blocking in the 1st and the 2nd former code portion 84,85 stably can be maintained.

Patent document 1: Japanese Patent Publication 4-84313 publication

Patent document 2: Japanese Patent Publication 41-9266 publication

Patent document 3: Japanese Unexamined Patent Publication 6-14806 publication

At the left and right leg of the training pants 60 that patent document 1 is recorded, as previously mentioned, in the scope from the upper end of waist side to the bottom of bottom of s trouser leg side, slide fastener 61 is installed, the pull head 62 of this slide fastener 61 is made to slide and be separated into 2 zipper teeth chains, thereby, it is possible to training pants 60 is split up into front body piece 63 and rear body piece 64.

Particularly, in the training pants 60 of patent document 1, for ease of operation slide fastener 61, the separable bottom end stop of slide fastener 61 is configured in the bottom of bottom of s trouser leg side, former code 82 is configured in the upper end of waist side.Therefore, when keeping the form of trousers making the chain denture of slide fastener 61 engage, the pull head 62 of slide fastener 61 is configured in the waist of the upper end becoming chain denture.

In general, the many uses of training pants have the cloth formation of retractility.In addition, when putting on training pants or being taken off, the waist portions of training pants is stretched.Therefore, when as the training pants 60 of patent document 1 when being configured at waist for pull head 62 during trousers form, all can apply the tension force in waistline direction when wearing off training pants 60 to waist, so the upper end being configured with the slide fastener 61 of pull head 62 is applied large lateral pull repeatedly at every turn.

Now, this slide fastener 61 uses the what is called such as without stopping pawl described later free pull head 62, because when wearing off training pants 60, the leading section of slide fastener 61 is subject to lateral pull, so have to pull head 62 effect the stress making chain denture detaching direction (below) via the chain denture of left and right, this pull head 62 is caused to become easy slip on the contrary mutually with the wish of user.Therefore, the chain denture existed about the leading section of slide fastener 61 is separated and cannot keeps this problem of trousers form.

In addition, when pull head 62 is like this subject to lateral pull and slides, pull head 62 keeps the posture tilted relative to chain denture to slide unreasonably sometimes.Now, the slide fastener coupling element brute force of the deutostoma of pull head 62 and chain denture collide, and meanwhile pull head 62 forces movement downwards, to be pruned this problem so there is this slide fastener coupling element sometimes by the deutostoma of pull head 62.

On the other hand, as slider for slide fastener, except above-mentioned free pull head 62, the pull head of band auto-stop mechanism is used: it possesses the stopping pawl that can enter relative to chain tooth path of navigation, exit, and the position of pull head desired by chain denture can be made thus to stop and keeping all the time.

Can consider, the pull head of this band auto-stop mechanism is used in the training pants 60 of patent document 1 and prevents pull head as described above from forcing the situation of sliding downwards thus.But the lateral pull acting on the leading section of slide fastener 61 when wearing off training pants 60 is large, so by means of only making stopping pawl being engaging in chain denture as in the past, be difficult to the halted state stably maintaining pull head.

Particularly, when employing the pull head of band auto-stop mechanism, even if do not make pull head slide into the position of the upper end being configured with former code, the position of pull head desired by chain denture also can be made to stop.But, such as, when wearing off training pants under the state pull head not being moved to the upper end position that former code configures, pull head is made to become easy slip because lateral pull concentrates on the position of pull head stopping, so in the same manner as the situation of above-mentioned free pull head 62, produce this problem of form that cannot keep trousers.

And, when employing the pull head of band auto-stop mechanism, under the state stopping pawl being projected into chain tooth path of navigation, pull head slides unreasonably to the detaching direction of chain denture, so slide fastener coupling element can be pruned by the deutostoma of pull head, and slide fastener coupling element also can be stopped pawl and prunes, the breakage that also there is slide fastener coupling element becomes this problem large.

In addition, the leading section acting on slide fastener 61 is difficult in order to make lateral pull when wearing off training pants 60, also can consider, it is such that such as described patent document 3 is recorded, and makes this strap end portion be formed as mountain shape the Partial Resection of the left and right sides in the strap end portion of zipper strip.

But, even if the strap end portion of zipper strip is formed as mountain shape, lateral pull also cannot be made when wearing off training pants 60 not act on the leading section of slide fastener, arbitrarily to slide this problem so wish that pull head 62 runs counter to user cannot be eliminated.And, in this situation, can new produce zipper strip self easily from the cut-out of band upper end rupture this problem, formed concavo-convex in the waist portions of training pants 60 and make exterior quality reduce this problem.

Summary of the invention

The present invention completes in view of above-mentioned existing problem, its specific purposes are to provide: even if be subject to lateral pull under the state that stops in the position of former code of pull head, also pull head can be suppressed freely to slide to the direction making chain denture be separated, and stably maintain the slide fastener of the engagement of the chain denture of left and right and to be sewed with the slide fastener of this slide fastener article coated, also be to provide: even if be subject to lateral pull under the state that stops in the position of former code of pull head, lateral pull also can be made to be difficult to directly act on the slide fastener of the band upper end that former code configures article coated.

In this situation, preferably, described sewing line also has the 2nd sewing unit formed continuously from one end of described 1st sewing unit, and described 2nd sewing unit is inclined at a predetermined angle relative to described 1st sewing unit.

The effect of invention

In slide fastener of the present invention, the former code of installing in the end side of the chain denture of the zipper strip of a side has: the 1st top stopper being connected to the shoulder mouth side end of pull head; And to be configured between the 1st top stopper and chain denture and to be connected to the 2nd top stopper of the deutostoma side end of the guide post of pull head.In addition, the full-size slidingly contacting the bandwidth direction of edge to opposite side edge from flange of the 2nd top stopper is set to, larger than the interspersed width between the guide post in the chain tooth path of navigation of pull head and flange.And being configured at least partially of the 2nd top stopper, can with the mode elastic deformation of shrinking at bandwidth direction.

At this, the shoulder mouth side end of so-called pull head refers to the end of the shoulder mouth side of at least 1 in the guide post of pull head, upper flange, lower wing plate and flange.The flange of so-called 2nd top stopper slidingly contacts edge and is, when the 2nd top stopper has entered in chain tooth path of navigation from the shoulder mouth of pull head, the side edge part (side surface part) of the 2nd top stopper slidingly contacted with the flange of pull head, such as when the 2nd top stopper has aftermentioned such fixed part and extension, the flange that the side edge part of the band inward side of fixed part becomes the 2nd top stopper slidingly contacts edge.

In addition, the opposite side edge of so-called 2nd top stopper be the 2nd top stopper with the end edge portion (side surface part) of the zipper teeth chain opposite side of the other side, when the 2nd top stopper has fixed part and extension, the side edge part of the band outward side of extension becomes the opposite side edge of the 2nd top stopper.And the interspersed width between the guide post of so-called pull head and flange, refers to the air line distance that linking with straight line to the internal face of flange from the sidewall of guide post, distance is the shortest.

Due to the former code in slide fastener of the present invention, have as mentioned above be configured in a side zipper teeth chain on the 1st top stopper and the 2nd top stopper, thus when making pull head slide into the position of former code, the 1st top stopper can be made to be connected to the shoulder mouth side end of pull head and pull head is stopped.

In addition, the 2nd top stopper, when pull head slides into the position being connected to the 1st top stopper, enters in chain tooth path of navigation from the shoulder mouth of this pull head.Now, due to the full-size slidingly contacting the bandwidth direction of edge to opposite side edge from flange of the 2nd top stopper, larger than the interspersed width between the guide post in the chain tooth path of navigation of pull head and flange, so the 2nd top stopper is while make to be shunk at bandwidth direction by elastic deformation at least partially, between the guide post passing through pull head and flange.

And, when the 1st top stopper is connected to the shoulder mouth side end of pull head as mentioned above or be about to abut before, the part of the elastic deformation of the 2nd top stopper recovers elasticity by guide post, and the 2nd top stopper is connected to the deutostoma side end of the guide post of pull head.Abut with the 1st top stopper and the pull head stopped thereby, it is possible to reliably being supported by the 2nd top stopper, thus stably can keep the halted state of pull head.

Like this in slide fastener of the present invention, by utilizing the elastic deformation of the 2nd top stopper, the 2nd top stopper with the size of the bandwidth direction larger than the interspersed width between the guide post of pull head and flange can be connected to the deutostoma side end of guide post and keep the halted state of pull head.Therefore, slide fastener of the present invention, the zipper teeth chain by means of only the folk prescription being configured with former code just can make the slip of pull head stop in precalculated position and keep this pull head.

And, in slide fastener of the present invention, 2nd top stopper is connected to the deutostoma side end of the guide post of pull head because recovering elasticity, so be connected to the moment of the deutostoma side end of guide post in the 2nd top stopper, can give change, produce little contact sound the operation feeling of pull head.

Thus, for the user of slide fastener, can feel that the 2nd top stopper is connected to the deutostoma side end of guide post, thus confirm that the halted state of pull head is kept by the 2nd top stopper.Consequently, user can be made habitually to carry out that pull head is slided into consciously be connected to the operation of the stop position of the 1st top stopper, so can significantly reduce because user does not make pull head slide until the unfavorable condition that is connected to the 1st top stopper and produces.

In slide fastener of the present invention, described 2nd top stopper has: be fixed on the fixed part on zipper strip; With extend from fixed part to band foreign side and be connected to the extension of the deutostoma side end of guide post, described extension has in through hole portion, band table back of the body direction.Thus, form with can enabling the 2nd top stopper elastic deformation, so when making pull head slide into be connected to the 1st top stopper, the 2nd top stopper can be made to enter in chain tooth path of navigation from the shoulder mouth of pull head, and extension elastic deformation is interted between guide post and flange swimmingly.And then at the extension of the 2nd top stopper by after between guide post and flange, extension recovers elasticity, thus extension can be made to be connected to the deutostoma side end of guide post and stably to keep the halted state of pull head.

In addition, in described patent document 2, describing as previously mentioned can the top stopper of elastic deformation, but the top stopper of this patent document 2, by abutting with another top stopper of relative configuration and make 2 top stopper be pressed on the flange of the left and right of pull head, and pull head is stopped.In contrast, make the 2nd top stopper of the present invention be connected to the deutostoma side end of the guide post of pull head stably to keep the halted state of pull head, this top stopper from patent document 2 is in structure and use completely different.

In this situation, described extension of the present invention is configured to, and has: the 1st side wall surface be oppositely disposed with the 1st top stopper; From the 2nd side wall surface that the 1st side wall surface is bent to form continuously; With formed continuously from the 2nd side wall surface and make the 3rd side wall surface that reduces gradually towards described chain denture from the size slidingly contacting the bandwidth direction of edge to described opposite side edge.

Thus, when the 2nd top stopper enters in chain tooth path of navigation from the shoulder mouth of pull head, 3rd side wall surface of extension first slidingly contacts with the guide post of pull head, so can, while promote the elastic deformation of extension, make the 2nd top stopper easily enter in chain tooth path of navigation and intert between guide post and flange along the inclination of the 3rd side wall surface.

Afterwards, the guide post of size the best part by pull head slidingly contacting the bandwidth direction of edge to opposite side edge from flange of the 2nd top stopper, the extension of the 2nd top stopper recovers elasticity, thus, 2nd side wall surface (particularly, by the 2nd side wall surface of the 1st side wall surface) of extension is connected to the deutostoma side end of guide post and stably can keeps the halted state of the 2nd top stopper.

On the other hand, in the state kept by the 2nd top stopper from pull head, when operation pull head makes it mainly be slided to the engagement of chain denture by the direction (detaching direction) of removing, because the 2nd side wall surface of extension is formed deviously, so the guide post of pull head can be made to slidingly contact along the 2nd the bending of side wall surface of extension, and promote that the elastic deformation of extension makes the 2nd top stopper enter between guide post and flange.Thereby, it is possible to the state that releasing pull head is kept by the 2nd top stopper, and pull head is slided to detaching direction.

In slide fastener of the present invention, the frangible portion of at least 1 that the engagement force local that chain denture has the chain denture making left and right is lowered.In the end side of the chain denture of the zipper strip of the opposing party, the pull head slide contact member of at least 1 configures in the mode relative with former code, the gauge of this pull head slide contact member is set to, interts the groove interval of groove large and less than the interval of the upper and lower wing plate of pull head than the band formed in pull head.In addition, the width dimensions on the bandwidth direction of this pull head slide contact member is set as following size: between the flange of the pull head when pull head that can intert is held in the 2nd top stopper and the 2nd top stopper.

Due to pull head slide contact member, there is gauge as described above and relatively configure with former code on the zipper strip of the opposing party, therefore, when being kept the halted state of pull head by the 2nd top stopper, even if the strap end portion of the former code side of slide fastener is subject to lateral pull, also owing to containing the 1st and the 2nd top stopper and pull head slide contact member in the chain tooth path of navigation of pull head, so chain denture can be suppressed from the end separating of former code side, and the engagement of chain denture is maintained.

And, in this slide fastener, from the engagement of chain denture and pull head is held in the state of former code, can not make pull head slidably, chain denture is separated from frangible portion and easily and promptly open slide fastener.Particularly, in this situation, the zipper teeth chain of left and right the pull head slide contact member be configured on the zipper teeth chain of the opposing party can be made to intert between the flange and the 2nd top stopper of pull head and easily deviate from from the deutostoma of this pull head, so can be made simply to be separated.

In addition, the zipper strip of the opposing party is configured with pull head slide contact member, pull head slide contact member has the sliding contacting part of more than 2 of being fixed on discretely on zipper strip, thus more effectively can improve the horizontal tensile strength of slide fastener.In addition, when making chain denture be separated from frangible portion, can more swimmingly the deutostoma of pull head slide contact member from pull head be pulled out.

And, in slide fastener of the present invention, the zipper strip of one side has the 1st analog chain tooth be configured between chain denture and the 2nd top stopper, the zipper strip of the opposing party has the 2nd analog chain tooth configured in the mode relative with between the 2nd top stopper and the 1st analog chain tooth, 2nd analog chain tooth is configured to, when the described chain denture of left and right is separated from frangible portion, the 1st analog chain tooth can be pressed and deviate from via deutostoma from the described chain tooth path of navigation of described pull head.

Owing to having the 1st and the 2nd such analog chain tooth, so, even if slide fastener is subject to lateral pull when pull head is held in former code, also can prevent pull head slide contact member from deviating from from the deutostoma of pull head by the 1st analog chain tooth, thus suppress the end separating of chain denture from former code side of left and right.In addition, when making chain denture be separated from frangible portion, 1st analog chain tooth is pressed, so can guarantee at the deutostoma of pull head the gap that the 2nd analog chain tooth and pull head slide contact member can be passed through, the 2nd analog chain tooth and pull head slide contact member can be pulled out swimmingly from the chain tooth path of navigation of pull head.

And, article coated according to the slide fastener of the present invention being sewed with the slide fastener with structure as described above, the pull head of slide fastener can be stopped by the 1st top stopper of former code, and stably keep this halted state by the 2nd top stopper of former code.Thus, even if apply lateral pull to the slide fastener upper end that remain pull head, pull head also can be suppressed to slide to the detaching direction of chain denture, thus stably can maintain the engagement of chain denture.

Therefore, at slide fastener article coated be such as described patent document 1 record such training pants, when wearing off training pants, even if the leading section being configured in the slide fastener of the waist portions of this training pants is subject to lateral pull, also stably can maintain the halted state of pull head, thus keep the form of trousers.

In such slide fastener of the present invention is article coated, slide fastener is sewn into slide fastener article coated on sewing line, there is the 1st sewing unit configured abreast with chain denture, one end of 1st sewing unit, be held in former code pull head guide post compared with configure by the position of another side (rear side) of chain denture.

Thus, such as slide fastener is article coated when bandwidth direction is pulled, can make lateral pull be difficult to maybe can not to act on do not configure the 1st sewing unit part (particularly, be held in former code pull head guide post compared with the slide fastener end of forward code side).Therefore, pulled at bandwidth direction even if slide fastener is article coated under the state being held in former code at pull head, also can more effectively suppress pull head to slide to the detaching direction of chain denture.

In this situation, described sewing line also has the 2nd sewing unit formed continuously from one end of the 1st sewing unit, and the 2nd sewing unit is inclined at a predetermined angle relative to the 1st sewing unit.Thereby, it is possible to lateral pull is difficult to or can not act on the former code side not configuring the 2nd sewing unit slide fastener end (particularly be held in former code pull head guide post compared with the slide fastener end of forward code side).And, can by the 1st and the 2nd sewing unit by slide fastener and slide fastener is article coated stably makes.In addition, during slide fastener of the present invention is article coated, sewing line also can not have the 2nd sewing unit and only be formed by the 1st sewing unit.

Particularly, 2nd sewing unit relative to the extended line of the 1st sewing unit to the direction of the opposition side of chain denture with more than 40 ° and the angle of less than 90 ° (preferably, more than 40 ° and the angle of less than 50 °) inclined, thus the lateral pull that the slide fastener end of forward code side compared with the guide post of the pull head being held in former code acts on can be made to reduce further, or lateral pull is made to be difficult to act on this slide fastener end.And then, be less than 90 ° (preferably less than 50 °) by making the 2nd sewing unit relative to the angle of inclination of the extended line of the 1st sewing unit, easily and stably can carry out article coated the making with slide fastener of slide fastener, can make zipper strip be sewn into till strap end portion slide fastener article coated on.

The slide fastener 10 of present embodiment has: the zipper teeth chain 1 possessing the pair of right and left of chain denture 3 at the relative band side edge part of zipper strip 2; The former code 11 that the upper end of the zipper teeth chain 1 on right side is installed along chain denture 3 and the 1st analog chain tooth 17; The pull head slide contact member 14 that the upper end of the zipper teeth chain 1 in left side is installed along chain denture 3 and the 2nd analog chain tooth 18; The not shown separable bottom end stop that the bottom of the zipper teeth chain 1 in left and right is installed along chain denture 3; With the pull head 20 that the mode can slided along chain denture 3 configures.

In addition, form pull head 20 and the separable bottom end stop of the slide fastener 10 of present embodiment, with the pull head generally used and separable bottom end stop in the past, there is the identical structure of essence.

That is, the pull head 20 of present embodiment possesses slider body 21 and is rotatably held in drawing of slider body 21 and climbs 22.In addition, slider body 21 has: upper and lower wing plate 23,24; Guide post 25 between the end linking this upper and lower wing plate 23,24; From the flange 26 of the extended in a direction close to each other left and right of the left and right lateral margin of upper and lower wing plate 23,24; Erect drawing of setting with the upper surface at upper flange 23 with door shape and climb erection column 27.

In addition, in the front end of this slider body 21, guide post 25 is sandwiched the shoulder mouth being formed with left and right therebetween, be formed with deutostoma in the rear end of slider body 21.And then, between upper and lower wing plate 23,24, be formed with the chain tooth path of navigation 28 being communicated with the shoulder mouth of left and right and the Y-shaped of deutostoma.

In addition, separable bottom end stop is configured to, and has: the intubate that the bottom of the zipper strip 2 in left side is installed along chain denture 3; The seat pipe that the bottom of the zipper strip 2 on right side is installed along chain denture 3; To be integrally formed with seat pipe and can for the socket of lower end grafting of intubate.

The zipper teeth chain 1 of the left and right in present embodiment has respectively: zipper strip 2; Be configured in plastic multiple slide fastener coupling elements 4 of band side edge part.Each zipper strip 2 of left and right, is made into or weaves into the band shape that width is narrow, and have: make the band main part 2a on slide fastener article coated (such as, training pants described later); The chain tooth installation portion 2b of slide fastener coupling element 4 is installed.In addition, the band ora terminalis of the chain tooth installation portion 2b side in zipper strip 2 is configured with core rope portion 5.

On the chain tooth installation portion 2b in the core rope portion 5 that comprises of the zipper strip 2 in left and right, by injection moulding along the plastic slide fastener coupling element 4 of strip length direction spread configuration, thus form chain denture 3.In this situation, each slide fastener coupling element 4 has: the engageable head 4a of oval in shape; The main part 4c on zipper strip 2 is fixed in the mode clamping core rope portion 5; To receive the neck 4b that thin mode is formed between engageable head 4a and main part 4c.

In addition, in the slide fastener 10 of present embodiment, at the central portion in the strip length direction (fore-and-aft direction) of chain denture 3, the frangible portion 6 (with reference to Figure 12) of at least 1 that the engagement force local being provided with the chain denture 3 making left and right reduces.This frangible portion 6, replaces the common slide fastener coupling element 4 with engageable head 4a, neck 4b and main part 4c, eliminates the slide fastener coupling element 4 ' of at least 1 only with main part 4c and neck 4b of engageable head 4a and formed by installation.

By giving lateral pull to the frangible portion 6 be arranged in this chain denture 3, can by this frangible portion 6 easily make left and right chain denture 3 be separated, and then, can from this frangible portion 6 forwards and rear chain denture 3 is separated successively.

The former code 11 of present embodiment is installed on the chain tooth installation portion 2b in the core rope portion 5 that comprises of the zipper strip 2 on right side.This former code 11 is by forming as follows: make the 1st top stopper 12 that the slip of pull head 20 stops; Be configured in the 2nd top stopper 13 between the 1st top stopper 12 and chain denture 3, these the 1st and the 2nd top stopper 12,13, by the synthetic resin injection moulding of material identical with slide fastener coupling element 4 being fixed on this zipper strip 2 on zipper strip 2.

1st top stopper 12 of former code 11 has: master looks rectangular main part 12a; From the engaging portion 12b that main part 12a is formed to being with inward side outstanding.Size (width dimensions) on the bandwidth direction of the main part 12a of the 1st top stopper 12 sets less than the interspersed width between the guide post 25 of pull head 20 and flange 26, and the part being formed as main part 12a can enter in chain tooth path of navigation 28.

In addition, the mode being connected to the flange 26 of pull head 20 when the engaging portion 12b of the 1st top stopper 12 is to enter in chain tooth path of navigation 28 in a part of main part 12a is formed, and because this engaging portion 12b is connected to flange 26, thus the slip of pull head 20 can be made to stop.

2nd top stopper 13 of former code 11 has: be fixed on the fixed part 13a on zipper strip 2; From the extension 13b that this fixed part 13a extends to band foreign side.The fixed part 13a of the 2nd top stopper 13, during to observe from face side, rectangular mode is formed, the ora terminalis (right side ora terminalis) of the band inward side of this fixed part 13a, as described later, become when the 2nd top stopper 13 enters from the shoulder mouth of pull head 20 and is interspersed in chain tooth path of navigation 28 slidingly contact with the flange 26 of pull head 20 slidingly contact edge 13c.

Gauge (size of above-below direction) on the above-below direction of fixed part 13a, set than the band formed between the extended flange 26 of the upper flange 23 from pull head 20 and the flange 26 extended from lower wing plate 24 intert groove groove interval greatly, and set than the upper and lower wing plate 23,24 of pull head 20 inner surface between interval little.

The extension 13b of the 2nd top stopper 13 is formed as having identical gauge with fixed part 13a.In addition, at the middle body of this extension 13b, be provided with at the through hole portion 13d of fore-and-aft direction.Because extension 13b has hole portion 13d, thus extension 13b elastic deformation can be made and at least shrink on bandwidth direction.

And the outer peripheral face of this extension 13b at least has the 1st side wall surface 13e, the 2nd side wall surface 13f and the 3rd side wall surface 13g.The 1st side wall surface 13e of extension 13b, relatively configures with the 1st top stopper 12, and configures at grade with the front end face of fixed part 13a.

The 2nd side wall surface 13f of extension 13b, configures continuously from the 1st side wall surface 13e, and is formed with bloating smooth curved laterally.Owing to being configured with the 2nd side wall surface 13f on extension 13b, thus as described later, when the 2nd top stopper 13 towards the deutostoma side of pull head 20 in chain tooth path of navigation 28 mobile and extension 13b has recovered elasticity time, the deutostoma side end 25a of the guide post 25 of pull head 20 can be made to be connected to the 2nd side wall surface 13f and to keep the halted state of pull head 20.

Have again, because the 2nd side wall surface 13f is formed deviously, so, when the state being such as connected to the 2nd side wall surface 13f from the deutostoma side end 25a of the guide post 25 of pull head 20 makes pull head 20 slide to the detaching direction (rear) of chain denture 3, the guide post 25 of the 2nd side wall surface 13f and pull head 20 can be made to slidingly contact while with the elastic deformation making the 2nd top stopper 13 to promote extension 13b in the mode that bandwidth direction shrinks, thus help the 2nd top stopper 13 to enter between the guide post 25 of pull head 20 and flange 26.

The 3rd side wall surface 13g of extension 13b, formed continuously from the 2nd side wall surface 13f, and be configured to, the size of 2nd top stopper 13 on bandwidth direction (that is, from the size slidingly contacting the bandwidth direction of edge 13c to the side edge part of the extension 13b relative with the zipper teeth chain 1 in left side of fixed part 13a) reduces gradually towards rear.

By configuring the 3rd side wall surface 13g at extension 13b, as described later when the 2nd top stopper 13 enters in chain tooth path of navigation 28 from the shoulder mouth of pull head 20, can while make the guide post 25 of the 3rd side wall surface 13g and pull head 20 slidingly contact, while the 2nd top stopper 13 is entered in chain tooth path of navigation 28 swimmingly, and the elastic deformation of extension 13b can be promoted and the 2nd top stopper 13 is shunk on bandwidth direction.

In present embodiment, full-size on the bandwidth direction of the 2nd top stopper 13, namely, from the full-size the bandwidth direction slidingly contacting the opposite side edge (the left side side edge part of extension 13b) relative with the zipper teeth chain 1 in left side of edge 13c to extension 13b of fixed part 13a to be set as, larger than the interspersed width between the guide post 25 in the chain tooth path of navigation 28 of pull head 20 and flange 26.

At this, the interspersed width between the guide post 25 of so-called pull head 20 and flange 26 is the interval between guide post 25 and flange 26, refers to the distance air line distance the most in short-term when linking the internal face from the sidewall of guide post 25 to flange 26 with straight line especially.

In the zipper teeth chain 1 on right side, between former code 11 and chain denture 3, be configured with the 1st analog chain tooth 17.Particularly, in the present embodiment, when stopping making pull head 20 be connected to the 1st top stopper 12 of former code 11, the 1st analog chain tooth 17 is configured at can the position of a part of deutostoma of shutoff pull head 20.In addition, the 1st analog chain tooth 17 has: be fixed on the main part 17a on zipper strip 2; From the head 17b that main part 17a extends to band foreign side.

In this situation, the head 17b of the 1st analog chain tooth 17 has the sliding contact surface that can slidingly contact with the 2nd analog chain tooth 18 described later be configured on the zipper teeth chain 1 in left side.In addition, this head 17b, by a part for its rear side excision being formed, and is configured to engage with the slide fastener coupling element 4 of front end of the chain denture 3 being configured in left side.

The pull head slide contact member 14 being configured in the zipper teeth chain 1 in left side of present embodiment, installs in the mode relative with former code 11, and has: the 1st sliding contacting part 15 being configured in front side; With the 2nd sliding contacting part 16 being configured in rear side.These the 1st and the 2nd sliding contacting parts 15,16, form the synthetic resin injection moulding of material identical with slide fastener coupling element 4 on zipper strip 2, thus are fixed on zipper strip 2 to be separated from each other independently form.

In addition, the 1st and the 2nd sliding contacting part 15,16, is formed to have substantially rectangular mode when face side is observed respectively, and in addition, the 1st sliding contacting part 15 is formed longer than the 2nd sliding contacting part 16 on strip length direction.In this situation, gauge on the above-below direction of the 1st and the 2nd sliding contacting part 15,16 is set to, than the band formed between the extended flange 26 of the upper flange 23 from pull head 20 and the flange 26 extended from lower wing plate 24 intert groove groove interval greatly, and than the upper and lower wing plate 23,24 of pull head 20 inner surface between interval little.

Thereby, it is possible to make the 1st and the 2nd sliding contacting part 15,16 be interspersed in swimmingly in the chain tooth path of navigation 28 of pull head 20.In addition, time in the chain tooth path of navigation 28 that the 1st and the 2nd sliding contacting part 15,16 is housed in pull head 20, even if slide fastener 10 is subject to lateral pull, 1st and the 2nd sliding contacting part 15,16 also can not from the band of pull head 20 intert groove depart from, but be connected to the flange 26 of this pull head 20, so the 1st and the 2nd sliding contacting part 15,16 stably can be remained in chain tooth path of navigation 28.

In addition, in the present embodiment, width dimensions on the bandwidth direction of the 1st and the 2nd sliding contacting part 15,16, although be set as more than the size specified in order to improve with the constant intensity of zipper strip 2, sets less than the interspersed width between the guide post 25 of pull head 20 and flange 26.

Particularly, width dimensions on the bandwidth direction of the 1st and the 2nd sliding contacting part 15,16 is set to following size: under pull head 20 is as described later held in the situation of the 2nd top stopper 13 (with reference to Fig. 4), can intert the gap formed between the flange 26 in the left side of the 2nd top stopper 13 and pull head 20.Thus, such as when making the chain denture 3 of left and right be separated from frangible portion 6, the the 1st and the 2nd gap of sliding contacting part 15,16 by being formed between the flange 26 in the left side of the 2nd top stopper 13 and pull head 20 can be made, thus easily the deutostoma of the 1st and the 2nd sliding contacting part 15,16 from pull head 20 is pulled out.

In the zipper teeth chain 1 in left side, between pull head slide contact member 14 (the 1st and the 2nd sliding contacting part 15,16) and chain denture 3, be configured with the 2nd analog chain tooth 18.2nd analog chain tooth 18 has: be fixed on the main part 18a on zipper strip 2; With the head 18b extended to band foreign side from main part 18a, there is the sliding contact surface that can slidingly contact with the 1st analog chain tooth 17 be configured on the zipper teeth chain 1 on right side in the header arrangement of the 2nd analog chain tooth 18.

In present embodiment, 1st and the 2nd analog chain tooth 17,18, when the chain denture 3 of left and right is in engagement and pull head 20 is held in former code 11, by making the head 17b of the 1st and the 2nd analog chain tooth 17,18,18b contacts with each other, and can prevent pull head slide contact member 14 and the 2nd analog chain tooth 18 from deviating from from the deutostoma of pull head 20.

On the other hand, when making the chain denture 3 of left and right be separated from frangible portion 6 as described later, owing to being configured with the 1st and the 2nd analog chain tooth 17,18,2nd analog chain tooth 18 can press the 1st analog chain tooth 17 makes it rotate, thus the pull head slide contact member 14 be configured on the zipper teeth chain 1 in left side can be made swimmingly to pull out (with reference to Fig. 6 ~ Fig. 8) from the deutostoma of pull head 20.

Then, in the slide fastener 10 of present embodiment with structure as described above, about the state that the chain denture 3 from left and right is separated, pull head 20 is made to slide to the engagement direction (top) of chain denture 3 and this pull head 20 action when former code 11 stops and keeping is described.

First, pull head 20 is slided to the engagement direction of chain denture 3, make the chain denture 3 of left and right enter chain tooth path of navigation 28 from the shoulder mouth of pull head 20, thus the slide fastener coupling element 4 of left and right is alternately engaged successively.

If make pull head 20 slide further, then after the chain denture 3 of left and right, the 1st analog chain tooth 17 be configured on the zipper teeth chain 1 on right side enters in chain tooth path of navigation 28 with the 2nd analog chain tooth 18 be configured on the zipper teeth chain 1 in left side from the shoulder mouth of pull head 20, afterwards, then the 1st and the 2nd analog chain tooth 17,18, as shown in Figure 2, the 2nd top stopper 13 be configured on the zipper teeth chain 1 on right side enters in chain tooth path of navigation 28 from the shoulder mouth of pull head 20 with the 2nd sliding contacting part 16 be configured on the zipper teeth chain 1 in left side.

Then, if the 2nd top stopper 13 and the 2nd sliding contacting part 16 relatively move towards deutostoma side in chain tooth path of navigation 28, then as shown in Figure 3, the edge 13c that slidingly contacts of the 2nd top stopper 13 slidingly contacts with the flange 26 on the right side being configured in pull head 20, and the guide post 25 of the 3rd side wall surface 13g and pull head 20 that are configured at the extension 13b of the 2nd top stopper 13 slidingly contacts.

Now, full-size on the bandwidth direction of the 2nd top stopper 13, although as previously mentioned, set larger than the interspersed width between the guide post 25 in the chain tooth path of navigation 28 of pull head 20 and flange 26, but the extension 13b of the 2nd top stopper 13 carries out elastic deformation and width dimensions reduces, thus the 2nd top stopper 13 can be made to intert between guide post 25 and flange 26.

Particularly, in the present embodiment, because the 3rd side wall surface 13g in the extension 13b of the 2nd top stopper 13 is inclined in the mode making the width dimensions of the 2nd top stopper 13 and reduce gradually towards rear, so by making the guide post 25 of the 3rd side wall surface 13g and pull head 20 slidingly contact, can while promote the elastic deformation of extension 13b, while make the 2nd top stopper 13 enter in chain tooth path of navigation 28 swimmingly, can intert between guide post 25 and flange 26 when not being hooked in guide post 25.

On the other hand, about the 2nd sliding contacting part 16 in the zipper teeth chain 1 in left side, as previously mentioned, the gauge of the 2nd sliding contacting part 16 set than the upper and lower wing plate 23,24 of pull head 20 inner surface between interval little, and its width dimensions sets less than the interspersed width between the guide post 25 of pull head 20 and flange 26.Therefore, it is possible to after the 2nd analog chain tooth 18, the 2nd sliding contacting part 16 is entered in chain tooth path of navigation 28 swimmingly.

And, when make by making pull head 20 slide upward further the 2nd top stopper 13 extension 13b elastic deformation on one side while to the deutostoma side relative movement of pull head 20 time, then the 2nd top stopper 13 and the 2nd sliding contacting part the 16,1st top stopper 12 and the 1st sliding contacting part 15 enter in chain tooth path of navigation 28 from the shoulder mouth of pull head 20.

Then, as shown in Figure 4, because the engaging portion 12b be configured in the 1st top stopper 12 is connected to the side flange 26 of pull head 20, so the slip of pull head 20 can be made to stop.In addition, while being connected to the side flange 26 of pull head 20 with the engaging portion 12b of the 1st top stopper 12, or be about to be connected to the side flange 26 of pull head 20 at the engaging portion 12b of the 1st top stopper 12 before, size the best part on the bandwidth direction of the 2nd top stopper 13, move to rear compared with the deutostoma side end 25a of the guide post 25 of pull head 20, thus the extension 13b of the 2nd top stopper 13 recovers elasticity.

Thus, the deutostoma side end 25a of the guide post 25 of pull head 20 can be made to be connected to the 2nd side wall surface 13f of extension 13b, so can reliably support by the 2nd top stopper 13 pull head 20 stopped because of the 1st top stopper 12, thus stably keep the halted state of pull head 20.

Particularly, in this situation, in the slide fastener 10 of present embodiment, the 2nd top stopper 13 is made to be connected to the deutostoma side end 25a of the guide post 25 of pull head 20 owing to recovering along with the elasticity of the 2nd top stopper 13, so be connected to the moment of the deutostoma side end 25a of guide post 25 in the 2nd top stopper 13, change can be brought to the operation feeling of pull head 20, little contact sound can be produced.

Thus, for the user of slide fastener 10, the deutostoma side end 25a that the 2nd top stopper 13 is connected to guide post 25 can be perceived, thus can confirm that the halted state of pull head 20 is kept by the 2nd top stopper 13.Consequently, user can be made habitually to carry out consciously making pull head 20 slide into the operation of the stop position abutted with the 1st top stopper 12.

In addition, as shown in Figure 4, in present embodiment, when pull head 20 is kept by the 2nd top stopper 13, the 1st and the 2nd sliding contacting part 15,16 be configured on the zipper teeth chain 1 in left side becomes the state be accommodated in the chain tooth path of navigation 28 of pull head 20.Particularly, the 2nd sliding contacting part 16, under the state left a little relative to the 2nd top stopper 13, between the flange 26 in the left side of the 2nd top stopper 13 and pull head 20.

And, the 1st analog chain tooth 17 fetch bit be configured on the zipper teeth chain 1 on right side becomes, with under the state (or close state) making the head of the 1st analog chain tooth 17 contact with the 2nd analog chain tooth 18 on the zipper teeth chain 1 being configured in left side and the slide fastener coupling element 4 adjacent with the 2nd analog chain tooth 18, by a part of locking of the deutostoma of pull head 20.

Pull head 20 is made to stop in former code 11 and keep like this, owing to being connected to the size of the bandwidth direction of the 2nd top stopper 13 of the deutostoma side end 25a of the guide post 25 of pull head 20, larger than the interspersed width between guide post 25 and flange 26, so the halted state of pull head 20 stably can be kept.

In addition, under the state that pull head 20 is held in former code 11, even if apply the lateral pull along making zipper strip 2 detaching direction of left and right pulls to the leading section being configured with former code 11 of such as slide fastener 10, in the chain tooth path of navigation 28 of pull head 20, former code 11 (the 1st and the 2nd top stopper 12,13) and pull head slide contact member 14 (the 1st and the 2nd sliding contacting part 15,16) are still stably kept, and the 1st and the 2nd analog chain tooth 17,18 is kept under the state making head 17b, 18b each other contact.Therefore, it is possible to prevent the zipper teeth chain 1 of left and right from deviating from pull head 20, the chain denture 3 of the left and right being in engagement is prevented to be separated.

In addition, when being applied with lateral pull to the leading section of slide fastener 10, due to the stress in the direction that the flange 26 of left and right is separated from each other from pull head slide contact member 14 and former code 11, so make this pull head 20 slide such power to the detaching direction (rear) of chain denture 3 to pull head 20 effect.But the pull head 20 of present embodiment is held stably as described above by the 2nd top stopper 13, so can effectively prevent pull head 20 from sliding to the detaching direction of chain denture 3.

Then, about the state (with reference to Fig. 4) being held in former code 11 from pull head 20 by pull head 20 to the action when detaching direction of chain denture 3 and rear slide operation, be described.

In this situation, be held in drawing of the pull head 20 of former code 11 and climb 22 by gripping and rearward pulled by pull head 20, the 2nd top stopper 13 abutted with the deutostoma side end 25a of the guide post 25 of pull head 20, the shoulder mouth side relatively towards pull head 20 is moved.Now, the guide post 25 of pull head 20, can press the extension 13b of the 2nd top stopper 13 to make this extension 13b elastic deformation, while make the 2nd top stopper 13 intert between the guide post 25 and the flange 26 on right side of pull head 20.

Particularly, in the present embodiment, the 2nd side wall surface 13f of extension 13b is formed deviously.Therefore, when the state of the 2nd side wall surface 13f being connected to the 2nd top stopper 13 from the deutostoma side end 25a of guide post 25 makes pull head 20 slide, by utilizing the curved surface of the 2nd side wall surface 13f, can while be promoted the elastic deformation of extension 13b by the 2nd side wall surface 13f, while make the 2nd top stopper 13 enter between guide post 25 and flange 26, so resistance to sliding can be relaxed when the slide of pull head 20 starts become large situation.

And, enter between guide post 25 and flange 26 by making the 2nd top stopper 13 like this, the state that pull head 20 is kept by the 2nd top stopper 13 can be removed, so pull head 20 can be made rearward to slide swimmingly, and the operation by making this pull head 20 rearward slide, the chain denture 3 of left and right can be made to be separated.

Then, about in the slide fastener 10 of present embodiment, to engage and pull head 20 is held in the state of former code 11 from the chain denture 3 of left and right, to be located at the frangible portion 6 of chain denture 3 for action when starting point makes chain denture 3 be separated successively, be described.

In this situation, by applying such as lateral pull iso-stress to the frangible portion 6 being located at chain denture 3, the chain denture 3 of left and right can be separated by this frangible portion 6, and then, by the zipper teeth chain 1 of left and right is pulled to the direction be separated from each other, as described in Figure 5, pull head 20 can be kept to be held in the state of former code 11 unchangeably, the slide fastener coupling element 4 of left and right is separated successively till the leading section and rearward end of chain denture 3.

Then, after slide fastener coupling element 4 engagement each other of front end of the chain denture 3 being configured at left and right is removed, by pulling the zipper teeth chain 1 in left side further, the 2nd analog chain tooth 18 pressing making to be configured on the zipper teeth chain 1 in left side is configured in the 1st analog chain tooth 17 on the zipper teeth chain 1 on right side.

Now, as shown in Figure 6, because the 1st analog chain tooth 17 and the 2nd analog chain tooth 18 do not engage each other, so the 1st analog chain tooth 17 is subject to pressing force from the 2nd analog chain tooth 18 and leads depending on rotating counterclockwise during observation, thus, opened by the deutostoma of the pull head 20 of the 1st analog chain tooth 17 shutoff, and the 2nd analog chain tooth 18 and the 1st analog chain tooth 17 slidingly contact and easily pull out from the deutostoma of this pull head 20 opened on one side.

And, at the 2nd analog chain tooth 18 from after pull head 20 is deviate from, pull the zipper teeth chain 1 in left side, thus, 1st sliding contacting part 15, after the 2nd analog chain tooth 18, contacts with the 1st analog chain tooth 17 while deviate from from the deutostoma of pull head 20, in addition after the 1st sliding contacting part 15, the 2nd sliding contacting part 16 contacts while deviate from from the deutostoma of pull head 20 with the 1st analog chain tooth 17.

Particularly, in the present embodiment, pull head slide contact member 14 segmentation is formed as the 1st sliding contacting part 15 and the 2nd sliding contacting part 16, so the 1st and the 2nd sliding contacting part 15,16 can intert between flange 26 in the left side of pull head 20 and the 2nd top stopper 13, deviate from swimmingly from the deutostoma of pull head 20.Thereby, it is possible to pull open the zipper teeth chain 1 of left and right and slide fastener 10 opened completely.

Like this, slide fastener 10 according to the present embodiment, due to be held in former code 11 at pull head 20 state under lateral pull is applied to the frangible portion 6 being located at chain denture 3, so, can when not slide pull head 20, make the chain denture 3 of left and right easily and promptly be separated from this frangible portion 6 and open slide fastener 10.

In addition, the slide fastener 10 of embodiment described above is configured to, and is provided with frangible portion 6 in chain denture 3, and the chain denture 3 of left and right can be made to be separated from this frangible portion 6.But the present invention, as previously mentioned, is also included within the slide fastener that chain denture does not arrange frangible portion.

Therefore, such as, variation shown in Fig. 9 is such, and chain denture 3 ' does not arrange the slide fastener 10 ' of frangible portion, when not having slide pull head 20, the chain denture 3 of left and right can not be separated.Therefore, in this slide fastener 10 ', the the 1st and the 2nd analog chain tooth 17,18 arranged to make pull head slide contact member 14 pull out from pull head 20 in the above-described embodiment can be omitted, and replace these the 1st and the 2nd analog chain teeth 17,18 and common slide fastener coupling element 4 is installed.
